RE: Intel ICH9R Raid5 supported?
|[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]|
Daniel - Keep in mind that dm-raid4-5 is still considered 'experimental.' Raid5 would work fine in a home environment as long as you do not plan on rebuilding after a failure [at the moment]. Since the dm-raid4-5 patch is still considered experimental, you should weight your risks of data loss. I have tested Heinz's dm-raid4-5 patch on several ICH systems and have had good success with it; even after pulling a drive out to simulate a failure. If a failure would occur, you would have the opportunity to back-up the data before the set completely failed. Raid5 rebuild functionality isn't quite here yet. But it will be! Everyone is still working hard to update dmraid to rebuild failed sets. - Eric >-----Original Message----- >From: ataraid-list-bounces@xxxxxxxxxx [mailto:ataraid-list- >bounces@xxxxxxxxxx] On Behalf Of Daniel Guzmán >Sent: Monday, January 28, 2008 9:47 AM >To: ATARAID >Subject: Re: Intel ICH9R Raid5 supported? > >Brian, thank you very much for your response. > >Since this patch is Alpha (experimental) software, how reliable is it for a >home environment? >Is development status enough for being reasonably safe from data lost? >Regards. > > >2008/1/27, Wood, Brian J <brian.j.wood@xxxxxxxxx>: > > Raid 5 is supported, but not in the base kernel as of yet (it's still >experimental).
